    Default Gigabyte GA EP45 UD3P Motherboard Temp

    Hi,

    I have a Gigabyte EP45 UD3P, with E8400 @ 4.2GHz, however when I run CPU intensive programs, ie. Orthos, video encoders etc. the "Motherboard" temp in Everest Ultimare goes up to over 50C, however, the temps of CPU etc in CoreTemp, Real Temp, and HWMonitor are all fine, could someone please inform me where the sensor for "Motherboard" temp is located, so that I can direct a fan onto it?




    Thanks...

    Thanks...
    Good question. My guess is that the MOBO temps are coming from a sensor right in the North Bridge chip. And 50c is perfectly fine I bet for your MOBO. (If thats the highest it ever gets. Maybe not if idle.) I used to get much higher than that when I had an 8800GTX Video Card or a GTX280 because the Video Card sits above my North Bridge chip and generated enormous heat that did not dissipate much if any at all. Even at Idle the temps exceeded 50c. YUK!!!

    But, once I upgraded to a GTX295, which is so radically different, than an 8800GTX or a GTX280 in the way it directs heat away to its side and away from the MOBO and out the back, that it brought my MOBO temps way down. Especially when idle. (Plus, my GTX295 idle temps are like 57c-63c versus my previous cards that idled practically 80c when just idle!) But with a GTX295 my MOBO temps are so much lower I don't even think about it anymore. The MOBO temps used to reach like 56+++c. Ouch! Now they are 50c tops when running full throttle for hours and hours continuously. YAY!

    (I'm ready to be corrected ppl for the sake of the education that goes with it. But I'm sensitive!!!)

    I believe that the MCH is where you want to direct your cooling efforts.

    I've read a post somewhere where someone removed the blue Gigabyte "bling" from the MCH as it does seem to impede airflow. I directed an Antec SpotCool at my MCH, but did not try to remove the blue plate.

    Thanks for your replys, I do have an Antec Spotcool at hand so will give that a go...

    The motherboard temp sensor is not located in the northbridge, or (unfortunately) any where near by.

    the Temp you are seeing is from a sensor on/near the southbridge. You can test this using a decent fan. Place the fan over the southbridge and you'll see it drop. Place it over the northbridge and it stays the same.

    If you require more confirmation, the question has been asked before. If you use the search, I'm sure you'll find at least one thread where Lsdmeasap has answered this.

    @Bee_Dee_3_Dee, Your 295 lowered motherboard temps likely because it is sucking air past the temp sensor on/near the southbridge,.

    I placed an Antec SpotCool fan over the Southbridge, and a few other locations on the motherboard (including the location suggested by Svengali), and it made absolutely no difference to the "Motherboard" temp (as shown in Everest Ultimate)...so it's back to the drawing board!

    Get MOBO temp reading from two or more other utilities.

    One is HWMonitor. Here, idk if you need 32 or 64 so DL for both is at lower part of the following page: CPUID

    I can't think of a second one, but recently I compared HWMonitor to Everest and they had identical readings on my PC.

    Think I have this sorted, I installed EasyTune 6, and opened up the "HWMonitor" tab, and opened up Everest Ultimate, and ran Orthos, and the "Motherboard" temp that rose up to 50+C corressponded to the "CPU" temp in "HWMonitor" tab in EasyTune, so it would appear that Everest Ultimate is simply reporting a CPU temp as the Motherboard temp, also opened up the utility "HWMonitor" and it reports System temp as 31C, and CPU as 55C, the same as EasyTune, so I will disregard Everest Ultimate reporting on this value, and stick with EasyTune and HWMonitor...so I will go with either Easytune or HWMonitor.

    Thanks for your help.

    I have this board as well and Everest does read the correct motherboard temperature on my board. The CPU is typically lower than the motherboard (at idle) since my graphics card blocks some of the air to the southbridge where the sensor is located. I have used a small fan directed to the southbridge and the motherboard temperature does come down.
